Claims.

This invention relates to an improved heel drilling fixture especially adapted for use in the manufacture of wooden shoe heels of the type which are fastened by nailless means to the heel 5 seats of shoes. Such heel fastening means lhave been disclosed in the patent to A. G. Eichhorn, No. 2,023,671, issued December 10, 1935, and involve a metallic plate fastened to the heel seat of a shoe and formed with downwardly extend- 1'0 ing keeper ears which are received within spaced slots extending into the body of a wood heel from the seating surface thereof, the keeper ears beingapertured for registration with a complemental bore extending transversely through 15 the heel body from the breast surface thereof, the said bore being adapted for the reception of a locking pin which is driven into said bore so as to occupy openings in the keeper ears of the metallic plate, whereby to prevent separation of 2b theheel from the shoe body.

rIt is of primary importance in the commercial ymanufacture of shoes involving heels having the laforesaid manner of .attachment that the transverse bore provided in the wood heels should bear accurate relationship with the keepers or ears of the metallic fastening plates, in order that when the locking pin is'inserted, the latter will definitely pass through the keepers or ears to secure the desired locking action.

Therefore, it is an object of the present invention to provide a. gaging fixture which when a wood heel is clamped or positioned therein, the said heel will be so located as to provide for the accurate drilling or boring of the lock pin receiving opening therein, so that said pin receiving opening will intersect the ear-receiving slots extending from the seating surface of the heel, so that when a p-in is subsequently driven into said opening, it will be brought into penetrating contact with theears of the fastening plates disposed in said slots.

For a further understanding of the invention, reference is to be had tc the following descrip-tion and the accompanying drawing, wherein:

Fig. 1 is a perspective View of the improved drilling fixture comprising the present invention;

Fig. 2 is a vertical sectional view taken through the same;

Fig. 3 is a horizontal sectional view on the line III-III of Fig. 2;

Fig. 4 is a detail sectional view taken through the jaw clamp on the line IV--IV of Fig. 2;

Fig. 5 is a vertical sectional view taken through a wood shoe heel of a type to which the Dlcscnt invention is particularly adapted.

Referring more particularly to the drawing, there has been disclosed in Fig. 5 a wood shoe heel, designated generally by the numeral l. The heel is so constructed that it may be fastened by means of nailless devices to an associated shoe body, in accordance with the disclosures in the aforesaid patent to Eichhorn. In attaining these ends, it is necessary to produce in the heel in a predetermined location a transversely extending bore or opening 2 which extends inwardly from 1'0 the breast surface 3 of the heel, the said bore or opening intersecting a pair of spaced relatively narrow slots d, which extend downwardly into the heel from the top or seating surface 5 thereof.

It is essential that the boreA or opening 2 should l5 be accurately located within the heel body and it is to the attainment of this purpose that the gaging fixture 6 comprising the present invention is particularly addressed.

The said fixture, in the specific form. of the 20 invention herein disclosed, comprises a metallic body formed to include a flat horizontal base 1, an upstanding vertical wall 8 and a short forwardly projecting and overhanging top wall 9.

The front surface of the vertical wall 8 is pro- 25 vided, intermediately of the height thereof With a horizontally disposed cross saddle l0, threaded bolts or screws ll being employed at the ends of the saddle to unite the same firmly in connection with the wall 8. The bowed intermediate 30 portion l2 of the saddle lil is disposed in registration with a slot or recess I3 formed in the front of the wall 8. This bowed portion is provided with a set of four parallel openings. adapted to adjustably and slidably receive positioning pins 35 I4. The rear ends of these pins are connected with a back plate l5, while the forward ends thereof project slightly and adjustably in advance of the front wall of the saddle lil, coil springs i5 being disposed to surround said pins 40 and are located between the plate l5 and the back of the saddle It. To vary the extent of projection of the forward ends of the pins I4 with respect to the front of the saddle, the wall 8 is formed with a threaded opening designed for the 45 reception of a threaded adjusting screw I1. By manually rotating this screw, the same will be brought into engagement with the plate I5, causing the latter to ino-ve in and out against the compression of the springs i6, and thereby varying 50 the extent of projection of the forward ends of the pins ld with respect to the front of said saddle.

The screw Il is equipped with a lock nut I8 in order to maintain the permanency of its adjusted positions. The top and bottom surfaces of 55 the saddle I are recessed to receive spaced tongues I9, secured in place by threaded fastening means 2U. The tongues I9 are so spaced that they may be received within the slots 4 provided in the heel I, while the forward ends of. the pins I4 serve as adjustable stops for regulating the clamping positions of the heel within the fixture.

In order to hold the heel in the dotted line position disclosed in Fig. 2, the forward end of the base I is provided with a pair of spaced apertured lugs 2l which receive a rock shaft 22 carrying at one end an actuating handle 23. Mounted on the shaft 22 between the lugs 2| for rocking movement in unison therewith is a clamping jaw 24. This jaw is formed to include a substantially V-shaped mouth 25 having angular surfaces 26 adapted for ready engagement with the rounded curvature of a shoe heel. The surfaces 26 may be covered by fabric, as indicated at 21, to protect a wood heel from damage when clamped in the yfixture. It will be seen that by actuating the handle 23, the jaw 24 may be readily rocked into holding engagement with the outer surfaces of a shoe heel blank mounted on the tongues I9, and moreover by the application of pressure to the handle, the seating surface 5 of the heel will be brought into and held in positive contact with the forward ends of the adjustable positioning pins I4.

The top wall 9 of the frame is formed with an opening 28 in which is positioned a guide bushing 29, the said bushing being provided with a longitudinally extending guide opening 3| through which may be inserted a drill or bit (not shown) in order that the drilling or boring tool may be fully and properly guided to produce the bore or opening 2 in the wood heel in the proper plane. With the use of. this instrumentality, high accuracy in workmanship is obtainable and likewise the time required in performing the operation is greatly reduced.
